Important: Additional Restrictions May Apply in Slough
Slough has 5 conservation areas. These include Colnbrook, St Bernard's School, St Mary's Church, Langley, Sussex Place and Clifton Road, Upton Park and Upton Village. If your property is in a conservation area, some or all permitted development rights may be restricted. For example, you may need planning permission for changes that would normally be permitted, including alterations to the roof, cladding, or extensions visible from a public highway.
Check with Slough planning department before starting work to confirm whether your property is affected by any special designations.
Permitted Development Rules for a Satellite Dish
Generally permitted under Part 25, Class A of the GPDO. Conditions apply to the dish size, position, and number of dishes on the property. In designated areas, additional restrictions apply to dishes on chimneys, front elevations, or highway-facing walls.
Conditions
- 1Maximum dish size: 1m diameter (or 0.6m if mounted on a chimney)
- 2No dish on a wall or roof slope forming the principal elevation or side elevation fronting a highway
- 3Maximum of 2 dishes on the property at any one time
- 4Must not be higher than the highest part of the roof or chimney (whichever is used for mounting)
- 5Dish must be removed when no longer needed
Size and Dimension Limits
- Dish diameter: 1m maximum (0.6m on a chimney)
- Maximum 2 dishes on the property
When Permitted Development Does Not Apply
- In designated areas (conservation areas, AONB, National Parks, etc.), no dish on a chimney, front wall, or roof slope facing a highway
- Listed buildings require listed building consent
- Additional dishes beyond 2 require planning permission
- Article 4 directions can restrict satellite dish installations
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to satellite dish installation. The dish and bracket must be securely fixed to prevent it becoming detached in high winds. Roof-mounted dishes should ensure the roof remains watertight.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Slough building control or use an approved inspector.
How to Apply in Slough
If you need planning permission for your satellite dish, you can apply through Slough's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Slough. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low risk for dishes within PD limits. In conservation areas, dishes on prominent elevations without permission are a common enforcement target. The council can require removal.
